Henryk Cederbaum (1863–1928) was a Polish lawyer and one of the noted members of Warsaw's bar in the early 20th century.
One of the best known was the trial of Aleksandr Barteniev, a Russian military officer who murdered his Polish lover, a noted dramatic actress Maria Wisnowska in 1890.
The governor's wife was set free while the shopkeeper was sentenced to three months in prison for "offending the higher authorities.
"[3] For his skilful yet unsuccessful defense of the shopkeeper, Cederbaum was expelled from the bar and sentenced to five years without the right of appearing in court.
[3][4] During his banishment from the bar, Cederbaum authored a number of legal handbooks for ordinary people, among them a guide on writing last wills and testaments.
